Tolong dong kak pakai besok kalau semua dijawab bakal tak like deh.... Question from @Siskapradnyawati

$1)\frac{75}{150} = ...\% \\ \frac{75}{150} = \frac{1}{2} \times 100\% = 50\%$

$2) \frac{13}{20} = \frac{13 (\times 5)}{20 (\times 5)} = \frac{65}{100} = 0.65$

$3)0.75 = \frac{75}{100} = \frac{3}{4}$

$4)4 \frac{1}{4} + \frac{2}{7} \\ = \frac{17}{4} + \frac{2}{7} \\ = \frac{119 + 8}{28} \\ = \frac{127}{28} \\ = 4 \frac{15}{28}$

$5) \frac{1}{3} + \frac{7}{9} - \frac{1}{18} \\ = \frac{6 + 14 - 1}{18} \\ = \frac{19}{18} \\ = 1 \frac{1}{18}$

$6) \frac{4}{6} \times 12 \\ = \frac{48}{6} \\ = 8$

$7) \frac{7}{9} \div 13 \\ = \frac{7}{9} \times \frac{1}{13} \\ = \frac{7}{117}$

$8)3 \frac{1}{2} \times \frac{1}{3} \div \frac{2}{5} \\ = \frac{7}{2} \times \frac{1}{3} \times \frac{5}{2} \\ = \frac{35}{12} \\ = 2 \frac{11}{12}$

semoga membantu

jadiin jawaban terbaik yaa

Siskapradnyawati kak bukannya no 7 itu dikali13 semuanya gk

nicken19 enggak

nicken19 itu kan 7/9 ÷ 13/1

Siskapradnyawati ooo mks

1. 75/150 = 1/2 = 50% (B)

2. 13/20 = 13 ÷ 20 = 0,65 (C)

3. 0,75 = 3/4 (A)

4. 4 1/4 + 2/7 = 17/4 + 2/7 = 119/28 + 8/28 = 127/28 = 4 15/28 (B)

5. 1/3 + 7/9 - 1/18 = 6/18 + 14/18 - 1/18 = 19/18 = 1 1/18 (D)

6. 4/6 × 12 = 48/6 = 48 ÷ 6 = 8 (C)

7. 7/9 ÷ 13 = 7/9 × 1/13 = 7/117 (B)

8. 3 1/2 × 1/3 ÷ 2/5 = 7/2 × 1/3 ÷ 2/5 = 7/6 ÷ 2/5 = 7/6 × 5/2 = 35/12 = 2 11/12 (A)

Maap kalo ada yg salah yaa
